France AMF AI: AMF Algorithmic Trading Supervision, ACPR Stress Tests & French AI Act Implementation
The French financial regulatory system — comprising the Autorité des marchés financiers (AMF) for capital markets and the Autorité de Contrôle Prudentiel et de Résolution (ACPR) for banking and insurance — has developed a sophisticated AI governance framework combining MiFID II implementation, AI-specific stress testing by ACPR, and France's active role in developing the EU AI Act. France is the second-largest EU financial market, and the AMF's algorithmic trading supervision program is among the most active in the EU.
ACPR AI Supervisory Stress Test — 2022-2023
Published: Results published 2023
Scope: Major French banks and insurers using AI in credit and fraud detection
Methodology: AI models tested under macroeconomic stress scenarios (recession, interest rate shock, credit crunch) to assess performance degradation under conditions different from training data
Key finding: Multiple institutions showed significant AI model performance degradation under stress — credit AI models trained on 2010-2020 data performed substantially worse under 2022-2023 macroeconomic conditions, with false positive and false negative rates outside acceptable ranges
Governance implication: AI models must include stress scenario testing as part of annual validation

Regulatory Risks and Compliance Challenges
The AMF's algorithmic trading supervision program is one of the EU's most active — conducting annual reviews of algorithmic trading governance at AMF-supervised investment firms, examining compliance with MiFID II Article 17 requirements, and issuing guidance on AI-specific algorithmic trading risks. The AMF has issued formal findings to multiple French investment firms for inadequate governance of AI trading systems — including inadequate pre-deployment testing and insufficient kill switch mechanisms.
France has been an active proponent of the EU AI Act and is implementing the Act's national supervisory arrangements. The ACPR and AMF are jointly preparing for their roles as market surveillance authorities for financial sector AI under the EU AI Act, with both authorities conducting pilot reviews of AI systems against the Act's high-risk classification criteria. France's CNIL (data protection authority) is coordinating with AMF and ACPR on GDPR Article 22 and EU AI Act interface cases involving automated financial decisions.

Frequently Asked Questions
What is the AMF's approach to algorithmic trading AI supervision?
The AMF conducts annual reviews of algorithmic trading governance at AMF-supervised investment firms under MiFID II Article 17. Reviews examine: pre-deployment testing documentation; annual self-assessment results; kill switch mechanisms and testing records; NCA notifications; and monitoring of AI algorithm performance. AMF examiners are specifically looking for whether AI trading systems are included in algorithmic trading governance frameworks — finding that many firms treat AI separately from traditional algorithmic trading systems.
What did ACPR's AI stress test find?
ACPR's 2022-2023 AI supervisory stress test found that multiple major French financial institutions showed significant performance degradation in their AI credit and fraud models under macroeconomic stress scenarios. Credit AI models trained predominantly on low-interest-rate, low-inflation data from 2010-2020 showed elevated false positive and false negative rates when tested under 2022-2023 macroeconomic conditions. ACPR has incorporated AI model stress testing into its supervisory expectations as a result.
How is France implementing the EU AI Act for financial services?
France's AMF and ACPR are jointly preparing to serve as national market surveillance authorities for financial sector AI under the EU AI Act. They are conducting pilot reviews of AI systems used by French financial institutions against the Act's high-risk classification criteria (Annex III) and developing supervisory examination protocols for conformity assessments. France's CNIL is coordinating on GDPR-EU AI Act interface cases. French institutions should expect formal EU AI Act examinations beginning in the 2025-2026 supervisory cycle.
What AMF guidance exists on AI trading system governance?
The AMF has published guidance on algorithmic trading governance that addresses AI-specific requirements. Key guidance areas include: AI trading systems must be covered in the MiFID II Article 17 annual self-assessment; AI systems must have tested kill switches that actually halt AI order generation; AI algorithm documentation must describe how the AI makes decisions in sufficient detail for examination; and firms must test AI algorithms under stressed market conditions before deployment.
How does the ACPR AI stress test apply to French insurers?
The ACPR extended its AI stress testing methodology to insurance underwriting and pricing AI — testing models under macroeconomic stress scenarios that could affect claims frequency, loss severity, and investment returns simultaneously. Insurers using AI in underwriting must assess how their models perform under conditions significantly different from training data, including catastrophic event scenarios. ACPR has incorporated AI stress testing into its Solvency II ORSA (Own Risk and Solvency Assessment) expectations.
